Acid And Bases

Question 1

How do you make a base through Alkali

Answer 1

Metal hydroxide
Metal Oxide
Iron Oxide
Copper Oxide
Base dissolved in water
Alkali is formed

Question 2

Ph-1

Answer 2

Strong acid

Question 3

What’s neutral?

Answer 3

Ph7

Question 4

What’s strong

Answer 4

14

Question 5

Alkali is a

Answer 5

Negative

Question 6

Acid is a

Answer 6

Positive

Question 7

What is a soluble salt

Answer 7

Reacting an Acid and a metal

Question 8

What’s the soluble salt formula

Answer 8

Acid+Metal-> salt + hydrogen

Question 9

What’s an insoluble base

Answer 9

Insoluble base is where it’s not reactive to water but is an alkali

Question 10

What’s the formulae for neutralisation

Answer 10

Acid+alkali-> salt+water

Question 11

How do you make copper sulphate

Answer 11

When copper and sulphur react

Question 12

How do you make an insoluble base through copper Oxide?

Answer 12

Copper and sulphate react to make copper sulphate

Keep adding copper Oxide and mix it with heat

Filter the solution through filter paper

Add copper sulphate to evaporating dish place on top of the beaker

After experiment you’ll see crystals

Question 13

How do you neutralise a solution? (Turn green)

Answer 13

Measure how much you want

Add acid

Once turned Green it becomes neutralised

Repeat experiment without adding indicated

Question 14

Hydrochloric acid makes chloride (what’s the formulae)

Answer 14

Hydrochloric acid+Mg-> magneschlorids+Hydrogen

Question 15

Sulphuric acid make sulphite. what’s the formula?

Answer 15

Sulphuric acid+ copper Oxide-> copper sulphate+water

Question 16

Nitric Acid makes nitrate. What’s the formulae?

Answer 16

Nitric Acid+sodium hydroxide -> sodium nitrate+ hydrogen
